Abstract

The horizontal grooves are located on the shaft of the needle, crossing the conventional longitudinal groove carrying the sewing yarn. The purpose is to provide a cooling effect on needles operating at 6,000 insertions a minute and bring the needle temp. below the 427 degrees F level experienced with conventional designs to work synthetic materials without heat damage.
